I don't do sports but I like watching tennis, ice hockey, gymnastics and diving when the Olympics are on. I like sports as a whole but not enough to do any or really watch them. I love walking but that isn't really a sport and I wouldn't watch it anyway.

I think walking is probably the healthiest and least risky form of exercise. Just a bit time consuming!
I agree with you, I don’t mind the time consuming part and I like the fact that you can do it anywhere all you need is space and your feet.
